It is a common fact that many people all around the world are facing visual difficulties. In this, some of the difficulty can be mitigated by eyeglass, contact lens or through treatment procedure According to studies, there are more than 20 million visually impaired people all around the world who needs to be cured. If more than one part of the eye got damaged, total loss of the vision may occur and cannot be cured by treatment. It is a common fact that these people are facing many challenges. With this scenario we have went through different reference papers and we found out different possible solutions and they are smart stick, smart wheel, drug treatment and prosthetic eyes. In these possible solutions, prosthetic eye is the best solution, and this can be done by integrating the engineering concepts and the physiological phenomenon of the human brain. The use of prosthetic eye was popular from ancient time onwards. The earliest known prosthetic eye was found in Shahr-I Sokhta, Iran which was made in 2900-2800 BC . Apart from that, evidence from the fifth century BC shows that the earliest prosthetic eyes which is worn outside the socket comes from Egyptian and Roman priests. These evidences clearly describe the use of prosthetic eye from the ancient times. Design of prosthetic eye in the 16th century was worn inside the socket which was made from gold or silver, with coloured enamel coatings . According to researchers, in 17th century more and more people came to this field like glass blowers who were making more realistic prosthetic eyes from glass. In 20th century, new discoveries were arisen in the field of prosthetic eyes and new materials were started to use to produce prosthetic eyes. In this 21st century also new researches for better implant material and design continues. This is the main reason we take prosthetic eye as our solution because there is space for us to incorporate the engineering technical skills.
